Diversity Statement
I grew up in a very diverse community, where over 300 languages and dialects were spoken and many of my childhood friends hailed from all over the world. Exposure to different peoples, traditions, and ways of thinking have been an integral part of my personal life, therefore, I value and welcome a culture that accepts people for the unique perspectives and experiences that someone may bring to my professional life. I strive to create an environment that allows all people to have an equal and safe voice in the classroom and lab and, when appropriate, allow for meaningful interactions that allow students and trainees to better understand and value others’ perspectives.

Teaching Philosophy
I am very enthusiastic about sharing knowledge and teaching. I believe it is important to acknowledge the numerous ways in which students learn, and how past personal experiences shape each student’s worldview and the learning process. Therefore, learning must be a journey that is tailored to students’ needs. I aim to bring an open mind and high expectations to the classroom, where I aspire to create an inclusive and welcoming environment that also encourages students to achieve higher learning outcomes.
